Abstract

An electrical distribution system is provided for selectively connecting an electrical power source to load devices comprising a panel and a plurality of switching devices mounted in the panel. Each switching device is electrically connectable between an electrical power source and a load device for selectively delivering electrical power to the load device. A control system controls operation of the switching devices. The control system comprises a programmed controller for commanding operation of the switching devices. The control system includes analog ports for selectively controlling analog load devices.
